yFigure l is a front elevation of the calendar embodying the invention; I

Fig. 2 is a top plan view thereof;

iig. 3 is a vertical sectional view on the line 3`3 of Fig. 1

Fig. 4 is a 4similar view on the line 4-.4 of Fig. l;

Fig. 5 is a perspective view of one of the these-stripsl are provided in theirupper and lower sides' with-grooves', which extend longitudinally thereof.. Panels 8 are slidably adjustably mountedu'pon Vmonthsv ofl th face of the board l near th thereof of year and one which may' be i The face adjustment; and theref the'face of the board l and are providedat t eir upper and lower iitting in the grooves 7 in the' strips 6, the tongue at the lower edge of the'lowermost panel fitting 'in the groove hese panels bear, in numerical order, ordinals yrepresenting the days in the several e year as 'indicated by thel numeral lO. A fixed panel l1 is secured to the and extends longitudinally thereof receives the tongue 9 at the up the uppermost he face of the letters 13 iiXed panel ll bears former 'being reprethe faces ofthe :similar klines of numeral '1.6 and in vertical aline,-

strips 6 e provided with division indicated by the defining spaces 17 located v ing color as s own clearly in Fig. l of the rawings.V It will' now be evident that the be positioned so as to g the ordinals borne thereby inver-tical alinement behev proper date letters uponthe pan l,v in .accordance with the week day upon which the first of each month ofa given year `will fall. In; order that the panel 8 may be conveniently adjusted, each panel is preferably provided at its left hand edge with a finger piece 19, anc in order panels may be es' with tongues 9 4 in the strip e upper lmargin f per edge of one of the month-date panels another of the openings 20, like securing element 22 being fitted through the registering openings for the purposel stated and as best illustrated in Fig. 4 ot the drawings.

rlhe panels 8, as stated, bear ordinals arranged in numerical order and representing the days of months, and the saidpanels are twelve in number and are arranged one be,-

neath another and are representative of the twelve-months of the year. Therefore, each panel will bear ordinals ranging from one to thirty or thirty-one, as the case may be, except that panel which is second in order and which is representative of the month of February and ordinals ranging from one to twenty-eight. To provide for leap year, the board l is provided near its right hand edge with a series of openings 23 corresponding to the openings 2O located within the channel which accomodates the panel 8 representative of the month of February, and one oi' more month day blocks 24 bearing the ordinal 29 as indicated by the numeral i provided with 25, the lblocks being tongues 26 corresponding to the tongues 9 Likewise each of the February panel 8. block is provided with an opening` through which and any one of the openings 23, a cotter pin (not shown) corresponding to the pin 22 may be fitted. Upon the occurrence of a leap 24 willbe fit-ted into the channel which receives the February panel and in position abutting against the right hand end of said] panel and secured in place by the Cotter theopenings pin which is passed through 23 and 27. ln order suitably identified, a panel 28 is secured up# on the face of the board l at the leftvhand margin thereof and is provided at its lower end with a tongue 29 seating in the groove 4 in the stri 3, the said panel being `provided uponits rear face at its upper en with a boss 30 seating in a recess 31 provided in the face of the said board 1. Also this end of the panel 28 is provided in its upper edge with a groove 32, and a block is seated and secured within a recess34 formed in the upper left hand corner of the face of the board landr is provided in its lower side with a groove 35 located abover and opposite the groove 32. The numeral 3G indicates numeral blocks which are provided at their upper and lower ends with tongues 37 slidably fitted into the grooves 32 and 35, and these blocks bear upon their faces ordinals which are indicated by the numeral 38, and the said stock and are arranged to effect a composition of ordinals representing the current 'within a. rabbet 4l formed in Vproj ect'ing which will of course bear,

' upper edge are provided vthe requirements,

7 .The blocks 36 are adapted year one ofthe .blocks that the various panels 8 may be cessity of dismounting blocks are selected from a year.l The panel 28 bears upon its face a series of month abbreviations 39 which are locatedl opposite the left hand ends of the channels in which lthe month panels 8 are arranged.

.lnorder to accommodate the stock from which the blocks 36 are selected and also to accommodate the Ablocks 24 heretofore referred to, a strip 4() is seated and secure the board lI at the upper edge thereof formed with a longitudinal groove in its upper marginal portion, this groove be.- ing adapted to receive the tongues 26 and 37 of the blocks 24y and 36. 4Likewise the. upper ec ge portion of the panel il is formed with a groove 43 which opposes the groove 42 and -formed with `a simi ar groove 44 likewise opposing the groove 42, these grooves 43 rand 44 being adapted to receive the tongues at the opposite ends of vthe'said blocks 24 and 36. ln this manner provision is made at the of the board for storing a suflicient supplyof ordinal blocks to meet all and in the ordinary use of the device, this stoel; will ly `concealed from view, or at least will'not be confused with the blocks or panels which are arranged upon the face of the board. to be secured in place in the same manner as the panels 8 an the blocks 24, as previously described.

inasmuch as the Acotter pins 22 are not subjected to any strain tending to pull them out from the openings 2() and'23 in the boardl l, but are merely intended torprevent sliding movement of the strips 8 -or pieces 24 as the `caseunay be, it is preferable that they be formed of spring metal and have their stein members bowed outwardly in opposite directions and somewhaty spread apart so'as to lit frictionally vin the openings in the said board l as shown clearly in Fig. 4 of he drawings. By thisy arrangement the pins may be conveniently removed and reinsert-y ed as occasion requires and without they Ilethe board or bending eiids of the stem members of the pins.

Having thus V described what is claimed as new ist' l. A calendar comprising a body member provided at one faccwitli a series of paral lel channels, month indicating means at one end of the channels, month-date bearing panels slidably adjustably mounted in the channels, the panels and the body member being pro-vided with openings adapted to be brought into registration in the adjustment of the panels, and a securing element the invention,
